Seen similar questions plenty of times here, but just wanted to run it by anyone that would like to chime in. New flooring, didn't know a thing about flange height until afterwards or course. Seems the simplest/popular is 2 wax rings w horn on top. Or should I over think it and replace the flange as it's easily accessible and go w a long shank one, like the raven PVC436SS 3x4 6" long? I believe the main pipe is 4" and the current flange is 3x4.
